SPECIFICATION forming part of Letters Patent No. 657,647, dated September 11, 1900.

Application filed May 27,1898. Serial No. 681,856. (No model.)

T0 (6 whom, it Wtcty concern:

Be it known that 1, CHARLES L. CURTIS, a citizen of the United States, residing at New York, (Brooklyn,) in the county of Kings and State of New York, have invented certain new and useful Improvements in Tube-Forming Machines, of which the following is a specification.

The object of my invention is to provide an improved machine for rolling strips of material, such as paper, into convolutions to form a body having a bore, such as a tube, one of the purposes for which such body or tube may be used being for the body of a firecracker,'firework, or similar article.

The invention consists in a tube-forming machine comprising a mandrel having a slot adapted to receive the edge of a strip while rotating and means for supporting and rotating said mandrel.

The invention also consists in a tube-form ing machine comprising a mandrel having means adapted to hold a strip while rolling it, a support for the mandrel, and means to cause said mandrel to move longitudinally to remove the rolled body from the same.

drel shown in Fig.

of parts that will be more fully hereinafter set forth and then pointed out in the claims. Reference is to be had to the accompanying drawings, forming part hereof, Wherein-- Figure l is a side elevation, partly broken, ot' a tube-forming machine embodying my invention. Fig. 2 is a perspective view of the mandrel. Fig. 2 is a transverse section taken through the mandrel on the line 0cm in Fig. 2. Fig. 2 is a similar section taken on theline'y y in Fig 2. Fig. 3 is a plan view of the machine, partly broken. Fig. 3' is a detail view of the strip to be wound upon the man- Fig. 4D is a cross-section of the machine through the mandrel. Fig. 5 is an elevation looking from the right in Fig. 1. Fig. (iisa verticallongitut'linal section of the machine. Fig. 7 is a view, partly broken, of a modified form of the mandrel. Fig. 8 is an end view thereof. Fig. 9 is a longitudinal section thereof on the line 9 9 in Fig. 8. Fig. 10 is a cross-section on the line 10 10 in Fig. 7, and Fig. 11 is a cross-section on the line ll 11 in Fig.- 8. 1

In the accompanying drawings, in which similarnumerals of reference indicate corresponding parts in the several views, 1 indicates a bed or frame which may be of any suitable constructiomand it is shown provided with ways 2 and a longitudinal slot 3. (See Fig. 4.) Upon the bed 1 are mounted a headstock 4 and tail-stocks 5 6. By preference the stocks at 5 6 are adjustable lengthwise of bed 1, and for this purpose I have shown said stocks provided with bolts 78 9, that project through the slot 3 of bed 1 and have nuts 7 8 9 for holding the stocks upon said bed, (see Fig. 6,) whereby said stocks may be readily adjusted. Said stocks are also shown provided with grooves at their bottoms to receive the ways 2, whereby they are properly guided and held upon the bed 1. (See Figs. 4 and 5.)

10 is a mandrel around which a strip 11, of paper or other suitable material, is adapted to be wound in convolutions, and 12 is asupport in the form of a rod, to which the mandrel 10 is adapted to be attached, and said rod is shown journaled in asleevc or hollowshaft 13, that is journaled in hearings in the head stock 4 and tail-stock 6. (See Fig. 6.) The rod 12' is shown provided with a threaded bore 12 to receive the threaded end 10 of mandrel 10, whereby the latter may be detachably connect-ed with the former.

14 is a keeper or cap shown threaded upon the end of sleeve 13 and having an aperture to receive the mandrel l0, and 15 is a supplemental guide in the form of a bushing or short tube havinga flange 16, which bushing sleeve 13. By providing bushings 15, having differentsized bores, mand'rels' of various sizes may be accommodated. The keeper 14 is shown bearing against the head-stock L, and thus assists in keeping the sleeve 13 in its hearings in head-stock 4. It is evident, however, that other means may be provided for guiding the mandrel p The rod 12 is adapted to be rotated by the sleeve 13 and also to have longitudinal movement within said sleeve. For this purpose have shown the following arrangement:

17 is a pulley shown encircling sleeve 13 and journaled upon a bearing 18,-w'h'-i-ch pro jects from head-stock A: and has a bore that receives sleeve 13. (See Fig. 6.)

19 is a finger secured to head-stock 4 and entering an annular groove 20 in pulley 17,; whereby said p'ulley'is guided and held u on the bearing v A 21 is a stud or pin projecting from pulley 17, and it is" adapted to engagea correspond-"l in'g stud or pin 22, that is carried by a sleeve 23', mounted u on the sleeve 13 and keyed thereto, as by a spline and feather 24 25, so

that it may have longitudinal movement upon sleeve 13 to engage-and disengage studs 21 22, said studs thereby forming aolutoh.

The sleeve 23 is shown provided with an annular groove 23, adapted to receive pins 26 from a shifting foil: 27, that is pivoted at .28' to bed 1 and has a handle portion" 29, by

which it may be shifted. The-rod 12 has op posed longitudinal'ly-d'i'sposed' grooves 30, in which feathers 31 32' are adapted to fit.

form of narrow blocks 31*3 and pass through opposed slots 33 in thes'leeve 13' nearits outer end, and thus enter the grooves 30, which heads 31 32 may be secured to saidsleeve by screws'34l. see Fig. 5.) Thusfihefeathers 31 3'2'1'ock the rod 12 to the sleeve 1 3, so

rod 12 to move longitud'inallyi's as" follows": The rod 12 is provided with extornai'worm or screw-threads 12",, that nofniall' y' project I beyond the tail-stock 6 and mesh with aworni- 5 wheel 36, secured up n a siiafta'i', join-pared in bearings carried by the tail-stock 6,. and 38 is a handle secured to shaft 37, whereby the same may be rotated, and whereby also the wheel 36 can be stopped from the rotation caused by the Worm 12". Thus when studs 21 22 are in enga ement pu l'lfey 1'7 will cause sleeve 13', rod 12-, and mandrel lO to rotate',

and during the rotation of said rod theworm 12 will cause wheel 36 to rotate, and thus rod 12 will not have longitudinal movement.

Fig. 5.) These feathers are shown in th The feathers 31am 3 sleeve 13'.

When it is desired to cause rod 12 to move longitudinally outwardly, the rotation of wheel 36 is sto ped, as by taking hold of handle 38, whereupon the worm 12 working upon wheel 36, will cause rod 12 to move longitudinally, and thereby to draw mandrel 10 into When it isdesired to return rod 12 and mandrel 1 0 to their normal operative positions, the wheel 36 will be rotated by hand, and thus push rod 12 inwardly.

The mandrel is adapted, as before stated, to receive and wind upon itself a strip 11, and one of the objects of my invention is to cau'se the mandrel to grasp and wind said strip without stopping its rotation.

For this purpose I have provided a mandrel which is constructed follows: Referring to Figs. 1,

2, 3, 4, and 6, the mandrel 10is provided With 1 a longi'tudinall'y-di'sposed slot 10", which slot enters said mandrel tangentially; At the free end of said mandrel is a bore 10, that is adapted 01 receive" a centering-stud 40, carried bytail-stook 5", whereby said mandrel is supported guided at its free end. At

one sideof slot 10 in the surface of mandrel 10 is out depression 10, which is adapted 'to r'eo'eive'a pointed end 11 of the' strip 11,

i (see Fig. 3 whereby' said strip can readily 2 enter the slot 10, and as the mandrel continues to rotate the metal at the sides of said slot will gripsai'd strip to wind it on the mandr el. 1n this case the end 11? of strip 11, ;afror the" latter is wound upon the mandrel,

will be bent inwardly across the boreof the body' or tubo made upon the man'dre'l, and in order to straighten out the same to cause it to follow the inner wall of the bore of thebody'ortu'he the slot 10 'from the point where it meets the bore l O is out on a curve at 10", j that leads to the end of the mandrel.

(See

Fig. By this means as the body or tube that is formed on the mandrel drawn from the same the curved po'rtion1'0 'of slot 10" ;will' cause the projecting portion n of strip If to wind or be pressed"outwardly, so as to 4 against the inner wall of the bore of said In some cases, however, I prefer that the strip 11 should have a straight edge-where it m'eetsjthe mandrel, and for this purpose the slot 10"" may be made parallel throughout, as shown in Figs. 7, s, 9, to, and

11, and said slot is shown arranged tangentiall'y, and b'yprei'eren ce two of such slots are used, as shown in said figures.

Instead" of havi'uga bore at its end the mandrel shown in Figs; 7, 8, 9', and 11 is provided with a cylindrical projection 10' to receive the flair-stock or a support 40, having a socket.

! In thislea'se as the strip 11 is fed to the mandrel while the samfe rotates the strip will enter the sl'ot10 and the mandrel will wind the strip upon itself.

In both cases it will b'eu'n- 1 derstood that as the slot 10 is located at one side of the" axial center of the mandrel afnd jar-ranged tangentially the strip can readily enter said slot as it is pushed along, notwithstanding that the mandrel is rotating at the time that the strip is pushed against the same.

Mandrels of different lengths can be used that are attached to a rock-shaft 43, hung in suitable bearings in the head-stock 4 and tailstock 5, and from'the shaft 43 projects an arm 44, to which is attached a spring 45, which is also suitably attached to the bed or frame 1, the tendency of which spring is to move the presser 41 toward the mandrel 10, and thus to press upon the strip as it is being wound upon the mandrel.

At 46 is a table or plate upon which the strip 11 may be placed and pushed to the man,-

drel by hand, the table 46 being shown carried by brackets 47, secured to bed or frame 1. (See Figs. 4 and 5.) At opposite sides of the table or plate 46 are located guides 48,

which serve to guide the sides of the strip 1],

so that the same shall be fed properly to man-j gagement and pulley 17 rotated, whereupon the rod 12 and mandrel 10 will rotate and the wheel 36 will be continuously rotated by the worm or threads upon rod 12. The strip 11' is placed upon table 46 and fed to the mandrel, and when it comes in contact with the same it will enter the slot 10 whereupon its edge will be'bent, and the mandrel will thus grip it and will wind it upon itself, some gum or other adhesive being preferably placed on the upper outer edge of the strip, so that as said edge passes-under the presser 41 it will adhere to the body or tube thus formed. As soon as the strip is properly wound the operator grasps the handle 38 to check the rotation of wheel 36, whereupon the worm or threads 12 of rod 12 while the latter continues to rotate will cause said rod to move longitu dinally outwardly, and will thus draw mandrel 10 with it, whereupon the body or tube formed on said mandrel will abut against the keeper 14, and thereby the mandrel will be withdrawn from said body or tube, which can drop away. The handle 38 is next rotated by the operator, whereupon wheel 36 will act to feed rod 12 and mandrel 10 back to their normal operative positions. Thus it will be understood that the mandrel 10 can continuously rotate, and all that the operator has to do is to feed the strips 11 to the mandrel and to cause wheel 36 to stop rotating and then to rotate the same, as may be required.

Itis evident that the mandrels can be formed otherwise than as shown, and that the means for causing rod 12 to move longitudinally can be altered, if desired and I therefore do not limit my invention to the precise details of construction shown and described, as they may be varied without departing from the principles thereof.
